Okay, so here is some code that when compiled on Fedora Core 6 works great, but when I compile and run it on OpenSuse 10 it gives back a seg fault when trying to join the 2nd thead.
#include <pthread.h>
#include <stdio.h>
int print_message_function( void *ptr );
int x = 1;

Hello everyone,
Today we are attempting to port some legacy C code to a 64 HP-UX machine at my company and there is kind of a strange error we ran into.
there is a small function they have defined called zgetenv that
accepts a char* and basically just does some null checking and returns ... (0 Replies)
Hi,
First of all forgive me if Xlib related problems does not go under this thread.
In my main program, im using Xlib`s XImage type object which contains a regularly updating bitmap, and maps the XImage to a Xwindow using XPutImage.
( XCreateImage is used to create the XImage. )

Hi
some help read............
I'm getting a segmentation fault when I run an AIX COBOL/Db2 program.
I initiate the program from the command line, but it hangs, and then when I press enter it generates a segmantation fault and produces a core dump.

Hello,
I have a header which I have to add to a sorted file, however if I use
cat header sortedfile > newfile, the operation takes 2 minutes as the sorted file is over 400mb.
I have noticed that when I sort the 400mb unsorted file, this only takes 14 seconds to create the output.

ddi_dma_nextseg - get next DMA segment
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
int ddi_dma_nextseg(ddi_dma_win_t win, ddi_dma_seg_t seg, ddi_dma_seg_t *nseg);
INTERFACE LEVEL
This interface is obsolete. ddi_dma_nextcookie(9F) should be used instead.
PARAMETERS
win A DMA window.
seg The current DMA segment or NULL.
nseg A pointer to the next DMA segment to be filled in. If seg is NULL, a pointer to the first segment within the specified win-
dow is returned.
DESCRIPTION
ddi_dma_nextseg() gets the next DMA segment within the specified window win. If the current segment is NULL, the first DMA segment within
the window is returned.
A DMA segment is always required for a DMA window. A DMA segment is a contiguous portion of a DMA window (see ddi_dma_nextwin(9F)) which
is entirely addressable by the device for a data transfer operation.
An example where multiple DMA segments are allocated is where the system does not contain DVMA capabilities and the object may be non-con-
tiguous. In this example the object will be broken into smaller contiguous DMA segments. Another example is where the device has an upper
limit on its transfer size (for example an 8-bit address register) and has expressed this in the DMA limit structure (see
ddi_dma_lim_sparc(9S) or ddi_dma_lim_x86(9S)). In this example the object will be broken into smaller addressable DMA segments.
RETURN VALUES
ddi_dma_nextseg() returns:
DDI_SUCCESS Successfully filled in the next segment pointer.
DDI_DMA_DONE There is no next segment. The current segment is the final segment within the specified window.
DDI_DMA_STALE win does not refer to the currently active window.
CONTEXT
ddi_dma_nextseg() can be called from user or interrupt context.
EXAMPLES
For an example, see ddi_dma_segtocookie(9F).
